Bryan Oviedo was admitted to hospital on Wednesday with bronchitis that could rule the Everton defender out of the FA Cup quarter-final against Chelsea on Saturday evening.

The Costa Rica international, 26, was taken to Whiston hospital for treatment in the early hours of Wednesday, although it is understood that the issue is not considered more serious despite an initial report he had been suffering from chest pains.

Oviedo later tweeted: “Thank you very much for your messages. I am hospitalized for bronchitis, but nothing serious. See you soon.”

The defender, who played 90 minutes in Everton’s 3-2 defeat against West Ham United, has been blighted by injuries during his time at Goodison Park, missing eight months in 2014 with a broken leg he sustained in an FA Cup tie against Stevenage.

Roberto Martínez’s squad was already affected by illness, with Gareth Barry not well enough to start against West Ham and Tom Cleverley missing out completely because of chest infections.

However, the latter definitely expects to be fit for the weekend as he looks to get Everton to a Wembley semi-final.

“I have been training fully and I’m ready for this weekend,” he told evertontv. “I will do everything I can to help the team get through to Wembley.

“We need to do well in the FA Cup this year. It’s important we get to Wembley and give the club a lift and give our fans something to shout about. We have to put in a performance on Saturday against a strong Chelsea team.”
